Need help: Ported Sub vs. something like a shaker?

[swoardrider]

Thanks for the help in the explanation. The ID10 is D4, so it should be running at 2 ohms, I remember discussing that with the installer. I did buy a sealed box as B520 suggested. After I move the sub over and reconnect it, I need to re-attack the LC2i setup to ensure gains are proper.

However, as you guys noted, I don't think my B&O sub should be still pumping on its own (it still moves when I turn off the JBL amp). I think I will have to live with the 10" sealed until I get out to Seattle in June - then I hope to connect with some trustworthy AZers who may be able to help with some hands-on assistance (Beers on me for any takers!).

Definitely remove the stock sub. The hole it leaves will provide a "port" for the sound to travel into the cab and sound quality will improve.
